Landcover/existing vegetation maps are fundamental, basic data needed for naturalresource management. Such maps are useful in a wide range of applications including land management planning, ecosystem assessment, inventory, wildlife habitat assessment, rare and sensitive species modeling, invasive species modeling, recreational activity management, and climate change analyses. As identified in the “2011 Information Needs Assessment”, this project evaluated existing land cover/vegetation maps for accuracy and utility for land management planning applications on the Chugach National Forest.

A summary report of a “Landcover Mapping Comparisons Project” is currently underway on the Chugach National Forest in which existing land cover/vegetation maps are being evaluated foraccuracy and utility for land management planning applications.

Purpose(s) of the Assessments- Help the user understand and apply- Help the mappers understand and improve•Purpose of the presentation- Briefly show agreement/accuracy informationalready developed by LANDFIRE

This document compares selected FRCC and LANDFIRE vegetation characteristics derived from simulation modeling with similar characteristics reconstructed from tree-ring data collected from
11 forested sites in Utah. Reconstructed reference conditions based on trees present in 1880 compared with reference conditions modeled by the Vegetation Dynamics Development Tool for individual Biophysical Settings (BpS) used in FRCC and LANDFIRE assessments showed significance relationships for ponderosa pine, aspen, and mixed-conifer BpS but not for spruce–fir, piñon–juniper, or lodgepole pine BpS.

This document was prepared to facilitate the LANDFIRE fuel verification process by providing guidelines that users should consider prior to this endeavor. If these guidelines are followed, the LANDFIRE fuel team can more readily use the critique to improve the data layers.

The interagency LANDFIRE project worked to produce quality products from available data sets. The Alaska and Hawai’i Milestone Assessment followed the processes outlined in the LANDFIRE Product Quality Control and Assessment Plan (PQCA Plan).

The Eastern Milestone Assessment followed the processes outlined in the LANDFIRE Product Quality Control and Assessment Plan (PQCA Plan), which was approved by LANDFIRE leadership and presents full disclosure of all pertinent information concerning the approach to assess quality of the LANDFIRE products.

is a report of the outcomes of the Western Milestone product quality assessment process for the LANDFIRE National Environmental Site Potential (ESP) and Existing Vegetation Type (EVT), Canopy Fuels and Fire Behavior Fuel Model (FBFM) spatial products.

The interagency LANDFIRE project is required to provide a Product Quality Control and Assessment Plan (PQCA Plan). The LANDFIRE Product Quality Working Team (PQWT) developed this draft work plan for review and adoption for implementation.

Compare the NPS assessment results with LANDFIRE assessment results to develop an overall, integrated review of LANDFIRE spatial product quality. The purpose is to inform potential users of LANDFIRE EVT—help them understand and apply the agreement assessment results in their applications.

To support the user community, LANDFIRE is committed to providing as much information as possible about the characteristics, quality and applications of all program products. Existing Vegetation Type (EVT) is a key product of the LANDFIRE Program. In addition to its use and importance as a spatial layer, EVT is used to develop other important downstream products such as Fire Behavior Fuel Models. We have focused on an EVT assessment first because it is a “directly mapped” product created from basic information about vegetation, vegetation transitions, and disturbance. It is not a “derived” layer.

Vegetation and fuel data submitted to LANDFIRE will be evaluated for inclusion into the LANDFIRE Reference Database (LFRDB). Each sampling unit must meet the described minimum requirements to be included in the LFRDB.

LANDFIRE 2008 Existing Vegetation Cover (EVC) and Existing Vegetation Height (EVH) spatial layers were assessed for quality within the forest vegetation types using FIA plots measured in 2008 and 2009. These plots were not used to develop the LANDFIRE EVC and EVH products, and thus constitute an independent assessment sample.
